Question

Of the processes listed below, which is not an important source of

acetyl-CoA?

a) pentose phosphate pathway

b) amino acid degradation

c) glycolysis

d) fatty acid oxidation

Answer 1

A) pentose phosphate pathway -

Overall Reaction for the Pathway

3 Glucose-6-Phosphate + 6 NADP+ + 3 H2O ---> 2 Fructose-6-Phosphate + Glyceraldehyde-3-Phosphate + 6 NADPH + 6 H+ + 3 CO2.

b) amino acid degradation

c) glycolysis

Only d) fatty acid oxidation is an important source of Acetyl CoA - Beta oxidation splits long carbon chains of the fatty acid into acetyl CoA, which can eventually enter the TCA cycle.
